Bestwood offers white boards with a high surface hardness on both sides. Importantly in comparison to conventional plywood and MDF boards, Bestwood PVC form white board doesn’t need a compulsory lamination for end-user applications. These boards can be directly applicable with beautiful and technical harden surface properties in comparison to even high-pressure laminate applied surfaces. However, these boards can be coloured or laminated to any finish.
These boards are built with ultra protective lamination that makes them waterproof and long lasting.
